STATES CHRONICLE – In spite of previous hopeful reports, neither vitamin D nor Calcium can prevent colon cancer even if patients are using above average daily doses. Many studies have delved into the benefits of taking vitamin D supplements due to their many improvements of a patient’s health. Colon cancer, however, is no longer considered among them.
It’s the fourth most common type of cancer in the United States, and this year has been diagnosed in 132,700 people, causing 49,700 deaths. Colorectal cancer can form from precancerous adenoma, which are benign tumors at first, but could be a cause of concern for the future.
Previous studies have lifted the notion that vitamin D or calcium supplements after removing the precancerous adenomas (otherwise known as polyps) could reduce the risk of developing more of the benign tumors in the future. However, a new study has unfortunately debunked the simple measure to avoiding the disease in the future.
And, according to co-author of the study, Dennis J. Ahnen, from the University of Colorado, these findings present with useful information in spite of the negative results. It’s as important to discover what works, as much as it is to find out what doesn’t. This could pave the way for future investigation by eliminating possible treatments before both time is wasted and lives are lost.
Researchers have conducted a study on nearly 2,260 people at 11 medical centers in order to test the notion. The participants had precancerous adenomas removed, with none remaining after a colonoscopy, and were further divided into four groups.
One was given 1,000 IU of vitamin D, and another 1,200 milligrams of calcium in daily doses. The other groups were given either both or neither.
No matter the difference in age, gender or study center, the results show no remarkable improvements on patients taking the daily supplements.
Out of the people taking high supplements of vitamin D, 42.8% developed additional adenomas, in comparison to the 42.7% of those who weren’t. Participants taking calcium doses did not fare better, with 45.3% developing polyps as opposed to the 47.5% who were not given the supplement. The impact was relatively minimal.
Overall, 45.7% of the patients who were taking both vitamin D and calcium saw to additional adenomas developing after the initial removal, while 48.2% saw to the same fate in spite of taking nothing at all. The study had been conducted over a period of 3 to 5 years, and essentially proved that neither of the two supplements can prevent colorectal cancer.
However, there were hopeful suggestions that the small differences in numbers could be enhanced after much longer treatment with. There might be some benefit if patients take vitamin D and calcium over a much longer period of time.
